I couldn't find any direct information on "settings Background Vector" in the provided search results. However, I can tell you that the concept of vectors is discussed in the book "Physics of Optoelectronics" by Michael A. Parker.

According to the book, linear algebra for vectors and operators is discussed in the context of quantum theory. The author explains the abstract form of linear algebra using Hilbert space, which provides a mathematical framework for understanding optical fields and their interaction with matter.

If you're looking for information on vector settings or background vectors in a specific context (e.g., graphics, physics, or engineering), I recommend searching for more general terms or consulting additional resources that may provide more relevant information.
